| 27 | A BFD has type <<bfd>>; objects of this type are the | |||
| 28 | cornerstone of any application using BFD. Using BFD | |||

| 233 | Error reporting | |||
| 234 | ||||
| 235 | Most BFD functions return nonzero on success (check their | |||
| 236 | individual documentation for precise semantics). On an error, | |||
| 237 | they call <<bfd_set_error>> to set an error condition that callers | |||
| 238 | can check by calling <<bfd_get_error>>. | |||
| 239 | If that returns <<bfd_error_system_call>>, then check | |||
| 240 | <<errno>>. | |||
| 241 | ||||
| 242 | The easiest way to report a BFD error to the user is to | |||

| 1420 | When testing an object for compatibility with a particular | |||

| 1422 | up certain fields in the bfd on successfully recognizing the | |||

| 1424 | failures possible at many points. On failure, the bfd is | |||
| 1425 | supposed to be restored to its initial state, which is | |||
| 1426 | virtually impossible. However, restoring a subset of the bfd | |||
| 1427 | state works in practice. This function stores the subset and | |||
| 1428 | reinitializes the bfd. | |||
